(E) Tetralogy of Fallot includes right ventricular hyperplasia, pulmonary stenosis, ventricular septal defect, and dextroposition of the aorta. It is a cyanotic congenital heart disorder with a dismal prognosis, unless surgically corrected. Anomalous pulmonary venous drainage (choice A) occurs when there is aberrant drainage of the pulmonary veins into the left atrium. Dextrocardia (choice B) is a mirror image inversion of the heart. Ebstein malformation (choice C)is a congenital abnormality of the tricuspid valve and right ventricle. Transposition of
the great arteries (choice D) is a congenital heart disease defined as the aorta arising from the right ventricle and the pulmonary artery originating from the left ventricle.
